COOK

STOVE.

comfort from heat, theconstruction being,

such that the major portion et the structure may be of Wood; to provide a stove having associated therewith compartments in which the food can be kept warm after having been cooked,` means being provided for the heat ingof hot Water in a household supply tank;

y andhgenerally to furnish a stove which is relatively simple and 'inexpensive in `construction, convenient and economical in practical use, and Which "will be relatively lightin Weightso 4that itA can be moved from y place toplace Without ditiiculty.

Thelforegoing and other objects are attained by means of a novel combination and arrangement of parts to be hereinafter described andclaimed, and nin order that the same ma be better understood reference should be had to the accompanying drawings forming a part of this specification.

In'v the drawings, wherein the same reference characters designate the same parts in all views, 1 s 1 i Figure 1 is a front elevation of a stove constructed in accordance with my invention;V

Figure 2 is a top plan View;

Figure 3 is a section on the line of Fiure; A c Y i'gure t is an end elevation;` i A i `Figure eis a cross section on the line 5-5 of `Eigure 2, and

gure 6 is a cross section on the lineG-t of, 1 i`,igure2. i Y e rlghe drawings illustrate What-now appears to be a 4preferred embodiment of the invention, but it is to ber understood that the invention is capable of othermechanical expression Without departing from the .spirit and scope ot the subject matter claimed hereinaitter. A, Y i e Referringl to thedrawings by reference characters, the stove comprises a rectangular #frame constructed mainly of `Wood,- preferably Philippine hard Wood. Ofcourse the frame can be made of metal or any other material desired. The frame includes upstanding cornerand intermediate posts 1, 1 respectively, suitably connected by longitudinal bars 2 and cross bars This frame serves as a support for the stove proper Which may be a more orless unitary metal structure lcomprising a fire-box fl at `one end,a subjaeent ash pit 5 separated from thefirebox by a grate Grand heat, flame and smoke passage?" leading from` the firebox 4 toward the chimney` S at the opposite end of the stove at which is also located the oven 9. e e i e The refractory clay bottom of the ashA pit 4 is supported by agalyanized iron plate l() which, as shown p, in Figures 3 and is supported by the longitudinal and cross frame .members 2, 3 atene end ot" the frame. The ash pit is approximately oncliird the length of the `frame and, as shown in Figure- 5, is about jone-`third the width of the trame being `disposed centrally thereof. The space at either side of `the ash pit l is iillcd with, lire `brick" 11, refractory clay or the like.` The .grate Sis supported upon thelire brick 11j, asshovvn in `Figure 5.

The fire compartment l `is dimensioned similarly te the ashpit 5 and the sides thereof are separated `from the outer walls oi.l .the stove proper by fire brick `or refractory clay 11,assh'own. e J p The Cold Water pi De 12 `(preferably rose copper) is shown (1* igures 1 and 5) leadingV from the household lrot Water tank 13 into the fire-box t and thence black to the hot Water tank 13. Thus the stove `supplies hot Water for household use in addition to being available for cooking purposes.

`In the end View, Figure 4f, is shou'n the fuel door 4 and the ash door 5*".

Figure 3 shows a sheet iron partition 1'1- orming the inner end Wall o'l theV ash pit and extending a substantial distance zbove the grate G. This partition` ll,"o'l"course, is coextensivewith the Width of the galvanized iron `sheet 10 deiiningthe bottom of the ash pit. oining the upper `end of the partitionlll is a sheet iron plate 15 of the same Width as partition 14 `and extending in the direction of the opposite end oit the iframe. Figure 3 also shows the l-iorizonta-l plate 15 as being offset at 15n at which point it supported by a cross member 3 of the iframe.

Plate 15 supports the oven 9 in spaced rey tiplicity of slots or openings b surrounding the oven 9, and between the walls thereof and the walls 16 of the chamber 17 so that the hot air coming `from the fire-box can circulate around the sidewalls of the oven and the walls 16 of the chamber 17.

in alined seriesand are 'located-immediately above the heat passageV leading from the tire-box to the'ov'em-that'is to say'one hole 19 is immediately above the lire-box, one intermediate the ends of theheat passage 7 and vtheotherimmediately above the oven i9. The heat passage 7 is enlarged beneath 2O holes19'and constricted intermediate holes 19, as indicated at 7 a, to a width slightly less than the width of the fire-box 4, the sides of the heat :passage being lined with lire brick or refraetoryclay 11, as shown. The bottom-ofthe heat pasageway 7 Yis also lined with fire brick 11. The interior walls of the stove,'thatfis to say the side walls of the firesbox it, heat passage 7 and the walls surrounding the compartment 17 are all lined with asbestos 'so as to-.keepl the heat from radiating outwardly and to conline the heat withiny the vrelatively small area desired.

i -Also the use .of insulating material, (fire brick Aand asbestos)V serves to effect an economyof fuel, in addition to avoidingthe subjection of the attendant to discomfort from Y heat. y"The-dotted linesv in'vFigure 2 clearly show theA confined area .leading from the -irebox tothe oven orfrather to chamber '17,- tlrrough which the "heat passes.

i .A chimney 8 is shown connected tov a cast -iron elbow 8a Vwhich extends through the V' back wallof the' chamber 17 (Figure 6).

vFigure l'showsV the oven'door 9a and also a register door 17@L which communicates with the chamber 17 whichsurrounds thev oven.

This register door can be open when it is Y desired to cool the oven orwhen it is desired to let somehot air out into the room, 'or for cleaning purposes.- 'Y

Th side and end walls of the fraineand valso of the stove proper may be constructed of wood. Iy have shown the back of the stove as being covered with a sheet of lgalvanized iron 25 which '1s coextensive in length and height with theentire unit.

The top'plate 18V of vthe stove proper is vshown as being'providedwith an extension at'V eithergside ofth'estov'e extending valong each 'longitudinaledge rThis extension is in the formof a rshelf 26'haviing an upstanding flange 526i1 at' its outer edge whereby the tile 27 can be laid upon the shelf and confined betweenv theflia'nge 26"v and the outer longitudinal edgeV of the plate18. -The shelf 26 is supported by means of brackets 28 these being shown in Figure 4. While shelf 26 is shown on but the two sides a similar shelf may be provided at each end without requiring the exercise of invention.

Of course, the plate 10, forming the bottom of the. ash pit, and the plate 15, to-

f gether with the upstanding metal partition 14 may all be formed from one sheet of metal bent to shape. A suitable valve or damper is provided which can be adjusted for diverting the products of coinbustion away from ar direct path to the chimney vforcing same to follow a tortuous course around the oven 9.

The area 30 incloscd by the frame of the device beneath the ash pit 5, heat passage 7 and chamber 17 may be utilized for keeping warm food which has already been cooked. As already mentioned this area is inclosed. lhere lire brick is used upon the bottoms of the ash pit, heat passage 7 0r chamber 17, the courses of such fire brick or refractory clay 'll are made thin enough so that enough heat will pass -in a downward direction to keep the subjacent space good-and warm. Also holesmay be cut in the bottom'asbestos lining 50 of passage 7. Accordingly I provide glazed 'doors 29 at the front of the device and opening into the area 30 beneath the stove proper. Of course the bottom of the food warming area, referred to, will be closed in by wood and also asbestos lining may be availed of so as to retain the heat.

-By'ernploying cleats 33 upon the posts l, 1 food supporting trays 34 can bepositioned within the food warming compartment or area 30.

From the foregoing description read in connection with the accom anying drawings the various features of a vantage', together with the details of construction of my stove are believed to be readily apparent to those skilled in the art. Inasmuch as the firebox and associated j'mssageways and cham` bers are separated from the sides of the stove and insulated therefrom the unit ma be made substantially of wood and is avai?I able for manufacture in places where metal is scarce. The ordinary diiculty with a stove for burning wood is that'it takes a tremendous quantity of Wood in order to produce suiicient heat to cook with. This is due to the fact that the heat is disbursed over a wide area. In my stove the heat. is confined to a relatively small area. at the center of the stove which area is, however, ample for cooking purposes.

'Having thus described my invention what I claim as new and desire te secure by Letters Patent is:

` 1. A cook stove comprising a wooden frame, a superstructine mounted upon said frame and having a fire compartment at lll) one end an oven compartment at the other end and a heat passage to establish com'- inunication between said lire compartment and said oven compartment, said superstructure having top, side, and bottom walls, the top wall of said heat passage having an opening, a heat plate` adapted to close said opening, the side walls of said superstructure being relatively thick and of insulating material to thereby materially restrict the width of said fireebox and passage whereby the top and bottom walls willV be subjected to a more intensified heat by reason of the limited area of said fire-box and passage, said passage being relatively enlarged beneath said heat plate, said frame being inclosed and having upstanding posts, trays supported by said posts for supporting food, and doors Vcarried by said post whereby access may be had to the inclosed portion of said frame.

2. A cook stove Vcomprising a frame, a superstructure mounted upon said frame and having a firev box, an oven chamber, an

oven in said chamber, a passageway connecting said fire box and oven chamber and located beneath the stove top, said passageway having an intermediate lineal area transversely widened to provide a heat pocket, webs for supporting said oven in said oven chamber, said webs being carried by the oven chamber wall and having openings therein to permit the free passage of gases about the oven, the top ot said oven lying in a plane with the bottom of said passage, a flue at one side of said oven chamber and spaced from the oven, a damper hinged below said flue opening and carried by the wall in which said iiue opening is located, said damper extending between and engaging the end walls of the oven chamber and having its outer end adapted to engage the top wall of said oven, whereby the hot gases from said passage may be diverted Y at will for passage about said oven.

In testimony whereof l aix my signature.
